I've been wearing this for 3 months and am pretty pleased with it. The display lights up at night so I can read it, the band is comfortable and easy to put on, pretty easy to operate, get sleep patterns, time, steps taken, heart rate, can set alarms and it collects data on how much exercise you've done. When close to my iphone (like in the next room close) it will alert me about texts and calls, weather,music.
The charger does not come with a wall plug in so I assume I'm supposed to use my computer to charge it (1x/wk) and it uploads data at the same time. My biggest gripe is that, as you can see in the photo, the information is seen up/down and, on my wrist, there's no way for me to read texts w/o taking the watch off bc the type is so small which is a pain! That holds true for any message that uses what looks to be 4pt type. My other small complaint, that might not bother others, is that there is a green light on the bottom (sensor?) that lights up when I move in bed and it's pretty bright (could take it off if you are not interested in sleep patterns). Because I've never owned another device like this, I've nothing to compare it to so take that into consideration. For the amount of info I can access, I'm pretty satisfied with it.
